The 46-year-old was on Greengate in Chadderton, near Oldham, when the collision happened at 10.30am on Tuesday.

She was taken to hospital, but died a short time later.

Greengate was closed near its junction with Victoria Avenue while traffic officers investigated.

Sgt Lee Westhead said: “We are keen to speak to anyone who was in the area around the time of the collision and I am particularly keen to hear from anyone who may have seen or spoken to the woman before she sadly died.

“She was wearing a distinctive white coat when this incident happened.

“We are doing all we can to establish how the collision occurred and are appealing to the public to help us."
